The plug has, ashoul..

B5 to the drawings I0 represents thebase ofthe yder 33` which rests on the II) of the burner, 55

whereby it is held in proper vertical position. The body of the plug comprises two pairs of upwardly extending ribs, one pair being indicated at 34, and the other at 35, the ribs depending from the head 36 of the plug, which is held in spaced relation to the base I0 of the Vburner by the shoulder 33, as shown in Figs. 2 and 4. By constructing the plug in the manner described, it serves to divide the mouth of the oil well into four separate passages, two at one side, and two at the opposite side, which discharge into the opposing ends of the outer and inner Vaporizing and vapor distributing grooves I5 and IG to insure even distribution of the vapor to said grooves in or above which combustion takes place upon lighting the burner, as described hereinafter. The upper extremity 31 of the plug is in the plane of the lower ends of the burner chimneys, as indicated in Fig. 2,y and forms a seat for portions of the chimneys 20 and 2 I. The plug is prevented from turning in the well by the contacting of two sides of its head with the wall portions 3| which connect the vertical walls I2 and I3 of the burner.

Suitable wicks for the burner are provided, one indicated at 38 'in the outer groove I5, andone at 39 in the inner grooveA I6. The inner wick 39 ene circles Vthe vertical wall I4 of the burner at the outer vside thereof, and the outer Wick 38 lies against the inner face of the outer burner wall I I, as shown in Fig. 1. The ends of the wicks are coiled upon themselves, as indicated at 4i?, to an extent sufficient to ll the grooves Within which they lie, said coils being preferably retained in proper position through vfrictional engagement with the walls of the burner with which they contact.- The coils 40 are placed diametrically opposite the distributing plug, the inner edge of the latter engaging and holding the wick 39 in contact with the wall I4, andthe outer edge of the plug engaging the wick 38 to hold it incontact with the outer wall II of the burner. The coils v4I! of the wicksV serve to close the grooves I5 and IE at a point opposite the distributing plug so that each groove is divided into two sections which insures a better and more even ow of the vapor within the grooves. The wicks are made of asbestos andreadily become saturated with the oil which flows into and partially lls the grooves when the burner is not in use, it being understood that at such time theA oil will nd its way from the Well through' the distributing passages of the plug, and that it will thus be discharged in opposite directions into the respective ends of the grooves lying immediately opposite said passages. I

It will be noted that the intermediate walls I2 and I3 of the burner are connected by radially extending ribs 4I which separate the air inlet openings IIa in the bottom of the burner.

Suitable connecting central and side walls 42 and 43 are provided between the burners, as shown in Fig. 1, the connections affording means for attaching the burner to a suitable support or supports, not shown.

The cover plate 24 for the chimney sections of the burner is provided with a handle 44 by which it can be conveniently removed from the sections. Y Y

The wicks of the burner can be conveniently lighted by means of a suitable torch inserted downwardly within the passages formed by the walls of the chimneys, or in any other preferred manner. y "`In the operation of the burner the supply of oil which has accumulated within the grooves I5 and I6 upon being ignited will be consumed in a comparatively short period, during which time the grooves I5 and I6 serve to some extent as vaporizing chambers, combustion of the oil vapor taking place at and above the tops of the wicks in the annular spaces between the chimneys. During this initial period of operation, the parts of the burner become heated, and the Walls of the oil well and the distributing plug therein will become suiciently heated to bring the oil within the well to the boiling point. The oil is thus converted in the well 25 into vapor which escapes through the four passages of the heated distributing plug into the grooves or vchambers I5 and I6, which thenceforth serve mainly as vapor distributing channels, though if anyfuel reaching these channels is incompletely vaporized, it may be completely or further vaporizedin these channels. The vapor rises from the channels into the spaces between the walls of the chimneys, mixes with air entering these spaces through the holes 23, and burns in these spaces. Combustion continues until after the valve in the supply line, not shown, has been closed.

The distributing plug is also advantageous as a means for preventing the flames from entering the oilvwell during the burning of the vapor in the chambers I5 and I6 and the overlying passages formed by the perforated walls of the chimney.
